Abstract: A staple cartridge is adapted to enhance cell migration towards a wound site when staples are placed in tissue. In order to enhance cell migration, the staple cartridge is adapted to create an electrical potential within the tissue in the area of a wound or cut line. In embodiments, the electrical potential is created within the tissue by using staples in spaced rows formed of dissimilar metals having different anodic indexes to create a voltage gradient in the tissue to enhance cell migration toward the cut line.

Abstract: An end effector for use with a surgical stapler includes a staple cartridge assembly movable relative to an anvil assembly. The staple cartridge assembly defines a plurality of retention slots and a cavity. The staple cartridge assembly includes a plurality of staples, a plurality of pushers, an actuation sled, a surgical buttress material, a suture, and an anchoring button. The actuation sled is configured for movement along a length of the staple cartridge assembly to sequentially engage the plurality of pushers to eject the plurality of staples through the respective plurality of retention slots. The anchoring button is configured to be received in the cavity of the staple cartridge assembly such that a portion of the suture is supported in the cavity to be severed by a knife blade of the actuation sled when the actuation sled is advanced distally.
